Naming divergences between authorities

50 materials whose GIA, FTC, CIBJO and Gem-A name columns are not identical — 30 pure wording differences plus 20 disclosure-qualifier differences.

About this comparison

Jurisdiction
Cross-authority comparison
Role
The materials whose GIA, FTC, CIBJO and Gem-A name columns on this site differ in the name itself, set side by side with the basis for each position that is on record and what it means for sellers; where a body has no position on record the column shows the entry's own English name, and the rows that differ only in the disclosure qualifier are shown on the entry pages.

Counts

50 materials carry naming differences between the four authority columns on this site; stripping the disclosure qualifiers in brackets leaves 30 pure wording differences, and the remaining 20 differ only in the disclosure qualifier. On 16 of the 50 only one of the four bodies has a position on record — the other columns show the entry's own English name, which is not on record here, not a statement by those bodies.

Where the recorded positions come from

Each authority position in the table below is one this site has on record. Where no position is on record, the English name of the entry itself is shown and marked as not recorded: that is not on record here, not a statement by the authority. The three columns count over different sets, so each header states its own denominator.
